IMPROVEMENT IN OULTWATORS.

my Stlgrbnlr rrfrmt in in flgrsr grams Q'idtlitld ant muting ;nrt at the same.

To ALL WHOM IT'MAY concnan:

Be it known that I, ISAAC B. MAI-ION. of Dunkirk, in the county of Hardin, and State of Ohio, have invented a new and improved Cultivator; and I do hereby declare that the followingis a full, clear, and exact description thereof, which will enablethose skilled in the art to make anduse the same, reference being had to the accompanying drawings; forming part of this specification, in which Figure 1 is a side view of my invention, the wheel nearest the eye being moved.

Figure 2, a plan orrtop view of the same.

Figure 3, a front, view of the same.

Figure 4, a rear view of a portion of the same. 1

Figure 5, a side view of an inner plough and portion of its standard pertaining to the same.

Figure 6, a section offig. takenin the line a x, fig. 5. I

Similar letters of reference indicate corresponding parts.

This invention relates to a new and improved cultivator, of that class designed for cultivating plants grown in hills or drills; and it consists in a novel construction and arrangement of the several parts, as hereinafter fully shown and described, whereby the inner ploughs may be moved or adjusted laterally to conform to the sinuosities of the rows of plants, all of the ploughs readily raised and lowered, and the principal parts of the machine rendered capable of being constructed of iron, so that it will be extremely strong anddurahle.

A represents. the axle of the machine, the ends of which are curved or bent downward, and" have the arms 13 B of the wheels C 0 attached to them by bolts a. These arm s13 are of bent or right-angular form, and have their upper parts constructed like sockets, to receive the vertical ends of the axle. To the rear side of the axle A there is attached a scat-frame, D, which is composed of a metal bar bent in the form shown clearly in fig. 2, secured by slots Z1 to the axle and braced by bars E, the lower ends of which are secured to the vertical bent ends of the axle by the lower bolts a which secured the arms B thereto. To the rear side of. the axle A there I is attached a guide-rod, F, on which a frame, G, is fitted and allowed to slide freely. This frame is provided at each end with two guides c, in which curved standards H. attached to plough-beams, I I, work; the front ends of said beams being attacheddly universal jointed 2 to arms c secured to thellower ends 'of a V-shaped bar, 3, which is attached to the draught pole K. On therear parts of the beams I I there are secured stirrupsL for the drivers feet; and it will be seen that the ploughs M whicharesecured to the bezims I I may be moved laterally either to the right or left, as may be required, in order to conform to the sinuosities of the rows of plants.- The beams I are constructed of two parts, e f, connected by a pivot, g, (see fig. 1;) and the ends of the parts e have a series of holes, 7:, made in them, through any one of which, and the partsf, a wooden pin, 2', passes; These pins 2', in case of the plouglis M meeting with any obstruction, will break, and allow the ploughs to yield or give, so that they may pass over the obstruction. The draught-pole K is of'wood, and is secured at its rear end to the centre of the axle A by a bolt, j, and is braced from the axis by the bars Is 7s; N N are plough-beams, the front ends of which are connected by pivots Z to the ends of the bar J; said pivots allowing the beams N to rise and fall, but not to move'laterally. The beams N, like-thc'beams I, are constructed of two parts, at n, con= nected by pivots 0, and the parts m secured in a working position by wooden pins 2). O is a shaft, which has its bearings g on the axle A. This shaft is allowed to turn freely in its bearings, and is provided with segments P, to the inner ends of which the plough-beams 11,}11 N, are connected by chains Q. A segment, it, is also attached to this shaft 0, to the outer end of which a lever, B is connected by achain, S;,said lever being attached to the seat-frame D. By actuating this lever B the plough-beams-may be 'simultaneously'raised and lowered. The beams N N are guided in their upward and downward movement by curved standards 1-, which pass through guides 8 formed at one end ofthe bolts a. The ploughs T of the beams N may be attached in the usual way, but the ploughs M of the beams II are attachedin a novel way, in order to admit of said ploughs being adjusted to throw the earth towards or from the plants. This is effected by having a. concave socket, t, attached to the rear side of the ploughs M; said sockets being fitted against cylindricah parts '11 cf the beams, and secured thereto by screw-bolts b, which pass through oblong slots w in the partsiu'of the'beams, and through loose sockets a at the rear of the parts a. (See figs. 5 and 6.) By this arrangement it will beseen that the plough M may be adjusted so as to cast the earth either towards or from the plants. U represents the double-tree attached to the drnught-pole'K, and having eyes 11 attached to its rein side, one near each end. Through these eyes a the upper ends of bars V V pass; the lower ends of said bars being pivoted to the lower ends of the her J. The whiflle-trees are connected to the bars V V, and by this means an efficient equalizer is obtained. I would remark that the frame G may be constructed of two parts, 6 b connected together by bolts a to admit of the beams I I being adjusted nearer together or further apart, as may be desired.

Having thus described my invention, what I claim .as new, and desire to secure by Letters Patent, is

1. The sliding-frame G fitted on the rod F at the rear of the axle A, in combiniztion with the plough-beams I I, connected at their front ends by universal joints (1 d to arms a secured to the lower ends of the bar J, and provided with curved sttindards H, which work in guides e attached to frame G, substantizilly as and for the purpose specified. I i v '2. The piough-beamsNN, connected by pivot-bolts to the lower ends of the bar-J, and provided with curved standards r, which work in guidesc formed at one end 'of the boltsa, which secure the arms B to the nxleAi 8. The shaft 0, provided with the segments P, to which the plouglbbeams'l I, NN, are connected by chains Q, and also provided with a segment, P,wto which a hhndJeVer, R, is connected by a chain S, all arranged for the purpose of raising and lowering the ploughs, substantially as set forth.

I 4. The whifi'le-tree bars V V, having their lower ends pivoted to the lower ends of the bar J, and their upper ends connected with the'double-tree U, substantially as and for the purpose specified.

5, The securing of the ploughs M to the beams II by means of the sockets t at the rear sides of the ploughs, the loose sockets a and the screw-bolts 2) whiclepess through the oblong slots w in the beams I I,

substantially as and for the purpose set forth. I
